FAN ATTACHMENT FOR ROCKING-CHAIRS.

SPECIFICATION forming part of Letters Patent No. 451,188, dated April28, 1891.

Application filed August 12, 1890. Serial No. 361,79 (No model.)

' to the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

The herein-described invention relates to improvements in fanattachments adapted to be operated by the movement of rockingchairs,cradles, and other like articles of furniture, and which is designed toprovide an effective and simply-constructed device which is readilyoperated and the fan-propelling mechanism of which works without theslightest degree of noise.

In the accompanying two sheets of drawings, in which similar letters ofreference are employed to indicate corresponding parts in each of theseveral views, Figure 1 represents a side View of one form of chairprovided with my improved fan attachment, certain parts of which areillustrated in section. Fig. 2 is a horizontal section taken on line xin Fig. 1. Fig. 3 is a side elevation of a casing containing thegear-operatingmechanism connected with the fan-propelling shaft. Fig. 4:is a top view of the same. Fig. 5 is a vertical section taken on line a:in Fig. at, and Fig. 6 is an end view of the casing shown in Fig. Fig.7is an enlarged vertical section of the shaft-propelling mechanismadapted to be operated by racks shown in Fig. 5; and Figs. 8 and 9 arehorizontal sections taken through lines y and 2, respectively, in saidFig. 7. Fig. 10 is a plan view of a slotted disk employed in connectionwith the clutch mechanism shown in Figs. '7, 8, and 9.

In the drawings, A indicates the base of the chair, upon which the samerocks by m cans of the rockers A.

To the cross-pieces a and a is attached in any convenient manner anupwardly-projecting arm 13, which is provided at its end with a socketedsleeve Z), and upon which is secured in any well-known manner a casing0, containing the shaft-revolving mechanism. Said casing is hollow,forming a chamber 0, and is provided upon its upper and lower sides withthe threaded portions 0 and c, the lower one of which is arranged withinthe socketed sleeve 12, while to the upper one is secured a tube 6. Thebody portion of said casing 0 extends on opposite sides of said portions0 and 0, being provided on its ends with diagonally-arranged holes and 0which extend entirely through the casing and form ways or guides inwhich reciprocate the racks (Z and d, connected with the back of thechair by means of links 61 and d Said racks are secured in anyconvenient manner to a bar or cross-piece d", and the links (1 and d arepivotall y secured thereto at its ends, passon said shaft, fittingloosely thereon, being in frictional contact with said pinions. On eachside of said disks and securedv to said shaft E are socketedclutch-collars e and a, provided within their socketed portions withserrations or teeth a and c As shown more especially in Fig. '7, thepinion 6 is provided with upwardly-projecting pins a which projectthrough a slot c in'the friction-disk (2 (see Fig. 8,) and upon saidpins are pivotally secured pawls e and upon said disk are arranged twopins o against which said pawls slide, and are thereby forced inengagement with the teeth or serrations in the socketed portion of theclutch-collar e by the movement of the pinion e. The pincontact betweenthe pinions, friction-disks, and clutch-collars, as will be evident fromFigs. 5 and 7. hen the racks are pushed forward, rack d operates pinione, causing the pawls thereon to slide against the pins e 011 thefriction-disk e whereby said pawls are thrown into lock ed engagementwith the teeth within the clutch-collar 6 which causes the shaft E torotate in the direction of arrow 1 in Fig. 8. At the same time thepinion e rotates in the direction of arrow 2 in Fig. 9, withdrawing thepawls 6 out of locked engagement with the teeth in the socketed portionin the clutch-collar c. On the return of the racks (Z and d pinion e isin locked engagement with clutch-collar (2 the same turning in thedirection of arrow 4:, Fig. 9, and the pinion e and friction-disk 6having its pawls withdrawn from thelocked engagement with the teeth inthe clutch-collare, rotates loosely upon the shaft E. IIence during thebackward and forward movement of the racks the shaft E will at all timesrevolve in the same direction. Thus it will be seen that the motion ofthe one pinion carries the pawls thereon against the relativelystationary pins on the friction-disks, thereby throwing the pawls intoengagement with the adjacent clutchcollar, while the pawls on the otherpinion are out of engagement with the teeth in the other clutch-collar.

From Figs. 8 and 9 it will be more clearly seen that the clutch-collarsare provided with. oppositely-formed teeth, and when the rack cl movesforward pinion e rotates the clutchcollar 6 in the direction of arrow 5,(shown in Fig. 5,) while the pinion e rotates loosely on the shaft E,and thereby does not operate the clutch-collar 6 During the return ofthe racks, rack 61 operates pinion e, which causes clutch-collar e tomove in the direction of arrow 6, and the other pinion 6 moves looselyon the shaft, from which it will be evident that said shaft E revolvesin but one direction. Thefriction-disks have been slotted, as shown,which causes the pawls to be nioved back and forth against the pins onsaid disks, and thrown into or out of engagement with the teeth on thesocketcd portions of the clutch-collars, according to the directions inwhich the racks move, as will be seen from Figs. 8 and 9.

In Fig. 1 it will be seen that the tube I), which contains the shaft E,is provided with a cap or collar b containing a bearing b through whichthe end of shaft E projects and rotates. A slightly-curved tube f issecured within said collar and communicates by means of another collar fwith a straight tube f which is provided with the collar f said collarshaving bearings in which is arranged the straight shaft E. A tube g,having elbows g and 9 is secured to the tube f and has arranged thereina straight shaft E Springs or flexible shafting f" and f connect theends of the straight shafts, as shown. NVithin the elbow g is arrangedthe spiral or spring g to which is attached a fan h in such a mannerthat when in operation the fan rotates in one direction above thechair-seat. Of course itwill be evident thatthe collar f can beconstructed so that the tube f can rotate upon said joint and the fanthereby turned to either side of the chair.

Having thus described my invention, what I claim is- 1. In arocking-chair or other seat, the combination, with the back thereof, ofa tube provided with a flexible shaft and a fan, a casing to which saidtube is secured, mechanism within said casing and secured to said shaft,racks for operating the same, and links connecting said racks with "theback of the chair, all of said parts being arranged and operating tocause said fan to revolve in one direction during the rocking motion ofthe chair, for the purposes set forth.

2. The combination, with the base of a rocking-chair or other seat, ofatube provided with means for fastening the same to said base, aflexible shaft in said tube provided with a fan, a casing O in said tubecontaining a shaft-operatin g mechanism, and racks working through saidcasing, said racks being connected at their ends farthest away from theback of the chair with links which pass on opposite sides of said casingand are attached to the back of the chair, all of said parts beingarranged and operating to cause said fan to revolve in one directionduring the rocking motion of the chair, for the purposes set forth.

3.

6. The combination of a rotary shaft arranged in bearings in a casing Cand provided with pinions e and e, fitting loosely thereon,reciprocatingracks moving in ways or guides in said casing on oppositesides of said pinions, slotted friction-disks loosely arranged on saidshaft and provided with pins thereon, pins on said pinions projectingthrough said slotted friction-disks, provided with pawls, a springbetween said pinions encircling said shaft, socketed clutch-collarssecured to said shaft, provided with teeth or serrations in theirsocketed portions, one of said clutchcollars being in locked engagementwith one pinion when the other clutch-collar is out of locked engagementwith the other pinion duringthe forward movement of said racks, and viceversa during the backward movement of said racks, causing the lockedengagement of the previously-disengaged clutch-collar and pinion andthrowing the engaged clutch-collar and pinion out of mesh, as and forthe purposes set forth.

7.
